3. Adjusting the Non-Image Width and Margin

Make adjustments in the following order: Adjusting the registration for leading edge margin adjustment

(COPIER>ADJUST>FEED-ADJ>REGIST, REGIST2)

Adjusting the image left/right margin (COPIER>ADJUST>BLANK>BLANK-L/R ) Adjusting the leading/trailing edge non-image width

(COPIER>ADJUST>BLANK>BLANK-T, B ) Adjusting the image read start (COPIER>ADJUST>ADJ-XY>ADJ-X, Y ) Checking the image margin

4. Adjusting the Reader Unit Horizontal Registration

If the lines of a grid pattern do not cross at a right angle or are distorted, adjust thehorizontal registration as follows for the reader unit. (Normally, such a problem is not like-ly, as adjustments are made at the factory.)1) Enter '6' under COPIER>TEST>PG>TYPE in service mode, and make a test print

(grid).2) Make a copy of the test print (grid).3) If the lines are distorted, adjust the horizontal registration for the reader unit as shown

in the figure. (Use the adjustment wrench FY9-1027-000).

Figure 2-5

4) Make a test print once again to end the work.

B. ELECTRICAL

1. When Replacing the Reader Controller PCB

1) Remove the two screws, and remove the two face plates; then, detach the reader unitlower front cover.

2) If you can make a check in service mode, Record the settings of the items (15 in total) shown in service mode on the reader

unit service label, and go to step 3). (You will have to remove the reader unit lowerfront cover.)If you cannot make a check in service mode,

Go to step 3).3) Remove the reader controller PCB as shown in V.B.1. "Removing the Reader

Controller PCB" in Chapter 4. Then, detach the EEPROM from the old reader con-troller PCB.

8) See that the copier will automatically turn off and then on. If you entered the wrong EEPROM serial No., the control panel will indicate 'E353'

(mismatch of serial Nos. between the rear controller PCB and the EEPROM). If so,enter the correct reader unit serial No. once again in service mode(OPTION>USER>SERIAL ).

9) Initialize the RAM on the reader controller PCB in service mode(FUNCTION>CLEAR>R-CON).

10) Enter the settings you recorded on the reader unit service label in service mode(COPIER>ADJUST>ADJ-XY , CCD; the same settings entered in step 2); thereafter,be sure to press the OK key).If you did not make a check in service mode in step 2), enter the settings indicatedon the service mode.

11) Select COPIER>FUNCTION>MISC-R>USE-LAMP in service mode.12) Turn the scanning lamp adjusting VR clockwise/counterclockwise until a beep is

heard; then, press the OK key on the control panel.(See II.B.7. "When Replacing the Intensity Detection PCB" in Chapter 12.)

13) Select COPIER>FUNCTION

Making Connections

1) Turn off the copier's control panel power soft switch and the reader unit rear powerswitch.

2) Remove the reader unit lower front cover, and the anti-noise plate on the switch.3) Connect the copier (downloading connector) and the PC with a bi-Centronics cable.

Be sure that the PC is off. Be sure to connect the 25-pin connector of the bi-Centronics cable to the PC, and the

36-pin connector to the copier.4) Slide the switch shown in the figure to LOAD position.

9. Checking the Photointerrupters

The machines photointerrupers may be checked either using a conventional meter orin service mode (by operating on the control panel of the printer unit). (If the reader unitis installed, you may use the control panel of the reader unit.)

a. Using a Meter1) SET the meter range to 30 VDC.2) Connect the - probe of the meter to GND on the DC controller PCB.3) Connect the + probe of the meter to the terminals (on the DC controller PCB) indi-

cated on the pages that follow.4) Make checks as indicated. (See the tables on pp. 2-16 ff.)

b. Using Service Mode Without the Reader Unit Installed (with the printer board installed)1) Connect the power plug to the power outlet; and while holding on the Menu key,

Enter/Online key, and Cancel keyon the control panel at the same time until StartSELF-TEST displays. The panel displays will show Display to indicate that servicemode has started after the printer unit checks itself.

2) Using the Menu key on the control panel, select SENSOR MONITOR.3) Press the ENTER key to select SENSOR MONITORING.4) Check to make sure that SENSOR MONITORING has appeared on the first row of

the display, indicating that at the mode in question has been selected.5) Turn on the sensor in question manually so that the result of monitoring will appear

on the second row of the display. The result of monitoring is indicated by means of a hexadecimal code (2 digits; either

xx or yy group).

Note:1.The notation zz shown on the display (2nd row) is for use at the factory for checks and is not relevant to servicing work.2.Each sensor has its own response time, some requiring as much as about 5 sec.

Be sure to allow an adequate period of time before making a decision on each sensor.

3.If multiple sensors are turned on at the same time, the result will be the sum of the codes obtained for all sensors (in hexadecimal notation).

4.To execute sensor monitor mode, be sure to remove the intermediate transfer drum, all cartridges, and secondary transfer belt assembly before starting service mode. (Otherwise, you could inadvertently touch operating parts.)

Further, you need to remove the following parts for respective sensors in view of the type of work to perform:

For PS1903 and PS5, the fixing assembly. For PS11, the upper cover assembly. For PS1207, the cassette 1. For PS1208, the cassette 2.

With the Reader Unit Installed1) Start service mode.2) Select COPIER>I/O>DC-CON or R-CON in sequence to bring up the screen shown

in Figure 2-13.3) Make checks as shown. (See pp. 2-16 ff.)

Of the variable resistors (VR), light-emitting diodes (LED), and check pins used in thecopier, those that are used in the field are discussed.

Do not touch VRs and check pins thatare not discussed herein. They are forfactory use and require special toolsand highly accurate adjustment.

Caution : Note:1. Some LEDs emit dim light even

when off. This is a normal condi-tion, and must be kept in mind.
